CRUDE-OIL BURNER.

Specification of Letters Patent.

Patented May 4., 19315.

Application filed July 25, 1914. Serial No. 853,214.

li ris vaporized and then passed through an airchamber where on leavingit is mixed with an increased admission of compressed air, thusproducing a perfect non-luminous flame which is emitted withconsiderable force at the outlet of the burner tube.

\Vith these and other objects in view the invention consists in theconstruction, combination and arrangement of parts as will its behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in 'the claims hereunto appended.

Referring to the drawings :Figure' l is a side elevation. Fig. 2 is anenlarged longitudinal section through the burner. Fig. 3 is a top planview thereof. Fig. '4 is a section on the line 4-4 of Fig. 2. Fig. 5 isa. sect-ion on the line 5-5 of Fig. 2. Fig. 6 is a section looking in anopposite direction.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings by numerals, 1 designates a cylindrical burnertube opening into the atmosphere at one end and hav ing its remainingend closed by a plate 2, the said plate being provided with a circularseries of openings adjacent its peripheral edge. The plate 2 is providedwith a concentrically arranged boss 3, and passing through the boss andplate is a passage 4;

flared in opposite directions from a point intermediate of its ends.Having screw threaded engagement with the boss 3 is a casing 5 formingan air chamber 6 and is provided with a pair of right angular arrangedscrew threaded openings and '8 Threaded into the opening 7 is a reducingnozzle 9 having a bore 10 of different dianieters, one end of said borecommunicating with the passage through a series of small apertures 11which have their axes disposed at an angle to the axis of the bore 10,while an 011 vapor pipe 14 communicates with the remaining end.

An oil pipe 12 leads into one arm of a Tcoupling, the other arm beingconnected by a solid plug to a second T-coupling. An

oil pipe 13 leads from the first coupling to the worm 15, and an oilvapor pipe 14 leads from the worm to the second coupling, the latterhaving a connecting pipe section leading to the bore 10.

Connected to the casing 5 by a plug 16 having screw threaded engagementwith the opening 8, is an air pipe 17 having communication at oneextremity with a source air under pressure and at its remaining iatremity with the air chamber 6. A valve 18 is provided for controllingthe amount of air fed to the flame, a channel 19 being provided betweenthe head 20 of the reducing.

nozzle 9 and the wall of the passage 4 for allowing the air in thechamber 6 to co mingle with the oil vapor.

A stand 21 formed of metal pipes is provided when the heater isstationary for any length of time, as when the process of heating heavyshafting and expanding hubs of wheels.

The device is attached to a tank containing crude oil, naphthas, oil oftar, vegetable oils or waste lubricating oil and this prodnet is forcedwith compressed air, of about 25 pounds pressure, into the pipe 12.thence through the pipe around the casing 53 into the worm 15 then backto wherc'the pipe 12 communicates with the nozzle 9. In the reducingnozzle the oil is reduced to a fine stream and is forcibly thrownthrough the apertures 11 into the interior of the burner tube 1 in theform of a fine spray. This fine spray is ignited and asthe worm 15becomes heated, the oil which passesthrough it is heated thus forming agas, which returns to the nozzle 10 and mixes with the auxiliary airwhere the channel 19 meets the apertures 11 and as a result of theproper feed of oxygen a perfect non-luminous flame is emitted withconsiderable force at the outlet of the burner tube.

If found necessary a check valve can be positioned in the oil pipebetween the burner and the oil tank for preventing back flow of gas oroil.

Having thus described the invention, what I claim is 1. In a burner ofthe class described comprising a casing having three screw threadedoutlets, a cylindrical burner tube open at one end, a plate closing oneend of said burner tube havin screw threaded engageinent with one of t eoutlets, said plate having a passage flared in opposite directions froma point intermediate of its ends, a re ducing nozzle having a bore ofdifferent diameters, screwed into another of the outlets, the bore ofsaid nozzle communicating with the passage of said plate, an oil pipecommunicating with the bore of said nozzle, and an air pipecommunicating with the in-' terior of outlet.

2. In a burner of the class described, comprising a casin havin threescrewthreadsaid casing, through the remaining 7 ed outlets, a cy indricaburner tube open at an oil pi e communicating with the bore of said nozze, and an air pipe communicating with the interior of saidcasing,through the remaining outlet.

3. In a burner oi. the class described, com-1 prising a casin havinthree screw threaded outlets, a cy indrica burner tube open at one end,a plate closing one end of said burner tube havin screw threadedengagement with one of t e outlets, said plate having a passage flaredin opposite directions from a point intermediate of its ends, a reducingnozzle having a bore of different diameters, screwed into another of theoutlets, a conical head on said nozzle having its passage in the saidplate for formingvan inouter surface spaced from the wall of thetervening channel, the bore of said nozzle communicating with the passae of said plate, through a series of angular y disposed apertures, theoutlet of the channel being disposed adjacent the outlets of theapertures, an oil pipe communicating with the bore of said nozzle, andan air pipe communicating with the interior of said casing, through theremaining outlet.

In testimony whereof I afiix my signature in presence of two witnesses.
